For starters, try drawing yourself a map of the area. Mappers
aren't the greatest thing to use with CF so I have always
enjoyed the ol':

system myself... but that's just me... -Anyway-. As your
making your map, if you see a sign or something in the room,
start examining them! (And don't forget keeping your full room
descriptions on can be a BIG help while exploring)

Now whether you just take note of the signs and return later
to review them, or take advantage of them when you find them,
by the time you've finished your map, you should have
completed the quest... or at least have a better understanding
of your situation.

But, all in all, Valg's advice is right on the money. So take
care, and Good Luck!
